Replacement Power Supply Behringer PSU-MX2 for MX1604A MX802A - Stable

In this review the Replacement Power Supply Behringer PSU-MX2 is evaluated for users who need a direct, affordable power adapter replacement for older mixers. The bottom line: this aftermarket AC power supply is best for owners of MX1604A, MX802A, MX1602A and DX100/500 mixers who want a straightforward, transformer-based unit that delivers the required AC17V output and a stable supply to restore console operation without modifying gear. It is not a universal replacement for mixers with different connector or voltage requirements.

Key Features

• 3-pin connector compatibility: Replaces the original mixer adapter using a CB-type 3-pin round connector so the mixer plugs in without rewiring.
• Transformer design: The built-in transformer provides more stable voltage to the console compared with some switching supplies, helping avoid hum and instability in older mixers.
• AC17V 600mA output: Delivers the specific AC17V 600mA rating required by the listed Behringer models to power preamps and analog circuits reliably.
• US AC3 prong plug: Ships with a US-style 110V plug and an approximate 2 m cable length, allowing flexible placement behind racks or under desks.
• Aftermarket alternative: Serves as a cost-effective replacement for discontinued or hard-to-find original adapters for Behringer and similar mixers.
• Solid build weight: At about 590 g the unit has the heft of a transformer-based adapter, which suggests durable construction.

Who It's For

This power supply is aimed primarily at owners of Behringer MX1604A, MX802A, MX1602A and DX100/500 mixers who need a direct replacement with the correct 3-pin power pinout and AC voltage. Live sound engineers, rental houses, and home studio users with these specific models will find it a practical repair part to restore a mixer to working order.

It is not intended for users whose mixers use a different connector type, voltage, or polarity, nor for those who require a worldwide input range; the unit is specified for 110V, 60Hz input only. If the original adapter had a different rating, or if you need a switching supply with universal mains, look for an alternative.

Pros & Cons

Pros

• Direct compatibility with several Behringer mixer models, avoiding cable mods or adapters.
• Transformer-based design gives stable AC17V output and can reduce noise compared with cheap switching supplies.
• Includes a 2 m cable and a US AC3 prong plug for typical setups in 110V regions.

Cons

• Limited to 110V, 60Hz input so it is not a universal international adapter without a step-down or converter.
• Aftermarket unit may differ cosmetically from original manufacturer adapters, though electrical specs are matched.
